Simple CSS Hack Can Steal Internet Passwords

A user on GitHub just posted an alarming exploit shows how a simple CSS hack can steal internet passwords. It’s kinda funny how you wouldn’t really think of CSS when it comes to vulnerabilities and hacking. Since CSS is only used to style a webpage, its threat level is generally considered to be relatively low. However, CSS does provide developers with very advanced selectors. In this case, if you wanted to select an input with the value of A in it and turn it red, then CSS allows you to do that.
